Question 51328: Solve each of the following systems by addition. If a unique solution does not exist, state whether the system is inconsistant or dependent.

2x + 3y = 1
5x + 3y = 1=
and this one too please!
x + 5y = 10
-2x - 10y = -20
Thank you so much for your help.

The first one becomes 2x%2B3y%2B5x%2B3y=1%2B1 which simplifies to 7x%2B6y=2. Solving for y we get y=expr%28-7%2F6%29x%2B1%2F3. The second set becomes -x-5y=-10 which becomes y=expr%28-1%2F5%29x%2B2. Their graphs are:
